Siri on your Mac
You can activate Siri with your voice on your MacBook Pro and use Siri for many tasks. For example, you can schedule meetings, change settings, get answers, send messages, place calls, and add items to your calendar. Use Siri to give you directions (“How do I get home from here?”), provide information (“How high is Mount Whitney?”), perform basic tasks (“Create a new grocery list”), and much more.
If you enable the “Listen for” option in Siri settings, Siri is available whenever you say “Hey Siri” or “Siri,” and immediately speak your request.
Note: To use Siri, your Mac must be connected to the internet. Siri may not be available in all languages or in all areas, and features may vary by area.
Turn on and activate Siri. Open System Settings, click Siri & Spotlight, and set options. If you enabled Siri during setup, on the 13-inch MacBook Pro, either tap the Siri button 
in the Control Strip on the Touch Bar, or press and hold Command-Space bar to open Siri. On the 14-inch or 16-inch MacBook Pro, press and hold the Dictation/Siri (F5) key 
to open Siri. Or click Siri & Spotlight in System Settings, then select Ask Siri. You can set other Siri settings, such as the language and voice to use.
Tip: You can add the Siri icon to the menu bar by selecting that option in Control Center settings. Then click the Siri icon to use Siri.
Hey Siri or Siri. On your MacBook Pro, you can simply say “Hey Siri” or “Siri” to get responses to your requests. Click Siri & Spotlight in System Settings, then choose the phrase you want to speak to start using Siri in the “Listen for” menu. When prompted, speak several Siri commands.
For convenience, “Hey Siri” doesn’t respond when the lid to your MacBook Pro is closed. If the lid is closed and connected to an external display, you can still activate Siri from the icon in the menu bar.
Tip: To learn about more ways you can use Siri, ask “What can you do?” at any time, or see the Apple Support article What can I ask Siri?.
Type to Siri. Type your requests to Siri instead of speaking them. Click Accessibility in System Settings, then click Siri on the right and turn on “Type to Siri.”
Show Captions. Show what Siri says on screen. Click Siri & Spotlight in System Settings, then click Siri Responses and turn on “Always show Siri captions.” You can also turn on “Always show speech” to have Siri transcribe your requests.
Drag and drop. Drag and drop images and locations from the Siri window into an email, text message, or document. You can also copy and paste text.
Change the voice. Click Siri & Spotlight in System Settings, then choose an option from the Siri Voice menu.
Throughout this guide, you’ll find suggestions for things you can use Siri for—they look like this:

“Show me my reminders.”
“What time is it in Paris?”
